冲击波效应
[解释]： 核爆炸形成的高温高压气团以极高的速度向外膨胀，猛烈压缩和推动周围介质所产生的高压脉冲波对人员和物体造成的毁伤作用及效果。核爆炸的冲击波是以超音速向四周传播的爆炸波，特性与传播规律和普通炸药爆炸的冲击波相适，但超压和动压值比普通炸药爆炸大得多。作用时间也长得多，当压力恢复到正常值以后，还有较明显的负压作用。威力为万吨梯恩梯当量以上的核弹在空中和地面爆炸时，冲击波是在较大范围内器杀伤破坏作用的主要因素，它作用于地面形成的地内压缩波和地震波，对爆心投影点附近地面和地下目标有很大破坏力。核弹在水下爆炸产生的冲击波，可摧毁水中舰艇和设施。冲击波对目标的杀伤破坏效应有直接和间接两类，直接效应主要是超压的挤压和动压的撞击所致，超压可引器人员内脏损伤和外伤，动压可使人体抛出、碰撞而造成伤亡，超压的高压和动压的冲击作用也可造成工事建筑和各种物体的破坏。间接效应是被受冲击波破坏的物体打击而间接造成的。冲击波的破坏随距离的增大而减弱。利用各种防护工事和有利地形可明显防护冲击波的毁伤。
